<NavigationView x:Name="MyNavigationView" PaneDisplayMode="Left">
    <!-- 导航菜单项 -->

    string tag = args.InvokedItemContainer.Tag.ToString();
    Type pageType = Type.GetType("YourAppName." + tag);
    MyFrame.Navigate(pageType);
}

protected override void OnNavigatedTo(NavigationEventArgs e)
{
    base.OnNavigatedTo(e);

    string pageName = this.GetType().Name;
    foreach (NavigationViewItemBase item in MyNavigationView.MenuItems)
